To all whom it may concern:

Be it known that we, Jonu 'i. FAGAN and Uneven/inn ll. QUACKENBUSII, citizens of the United States, and residents of Cleveland, county of Cuyahoga, State of Ohio,

have invented certain new and useful Improvenients in EXh-austing-Machines, of

ferred successively to each of a series of pumps. The said pumps are all stationary and it is necessary, therefore; for the apparatus to include a valve having members movable relatively to each other, which valve is located not only between the lamps and the'preliminary pumps, but also between said lamps and the final pump. The

valve fitting must be very good in order to preserve the high vacuum of the lamp in its final form and has caused considerable trouble. I

' One of the objects of our inventlon is to provide an apparatus in which this valve trouble will be largely obviated.

5 and the aforesaid vaive parts may be utilized According to our invention, during all except the preliminary stages of the evacuation, the; lampsare' connected directly to the 40 final pump Without theinterposition of a. valve. This isaccomplished by mounting the final pump to move with the lamps. In

its preferred form the machine is rotary and a number of the said finalv pumps are provided, each being connected to a predetermined number of lamps, the said pumpsbeing mounted on the rotary carrier with.

the said lamps. It is preferred to have a rough pump for preliminary evacuation,

and this may be stationary, with a valve having relatively rotatahi -parts interposed between the same and the. amps. It is preferred also to have astetionary backing pump in connection with the final pumps,

for this purpose. However, the vacuum to! be preserved in each case is not-. 'very high,

PatentedJen. 2, 191.7.

and therefore, the use of a. valve does not,

cause difiiculty.

Our invention also comprises improved means for heating the bulbs during evacuation and means for opening and shiftin the heating means to allow the removal 0 the exhausted lamps and the insertion of new lamps. 1

Our invention alsocomprises means for connecting and disconnecting the lamps. to,

the rough pump andto the final pump.

Various other features of our invention will appear from the detailed description of a species thereof which follows and from the accompanying drawing illustrating the In the drawing, Figure 1 is an elevation f of one machine embodying our invention; Fig. 2 is a. detail view of the tripping bracket-which operates various parts; F ig;

Referring now to the drawing, it will be seen that the machine comprises a rotary table 10 upon which are mounted the final pumps 11. which, as shown, are eight in number, although it 1S obvious that any desired number of pumps may be used. The said pumps are preferably of the oil type which is well known in connection with this art. The final pumps and the rotary table may be driven by the same source of power, which as shown in F igs. 12 and 13, may be the motor 12. The said motor drives a pallev 13 mounted on shaft 14. As shown in Fig. 11. the shar't ll carries at one end the bevel pinion 15. This, as shown in Figs. 1 and 3, engages the horizontally disposed bevel-gear 1b, which is fast to the central shaft or column 17 carrying a bevel gear 18. with which engage the bevel pinions 19 on the shafts '20 of the several final pumps. As shown in Fig. .14, a clutch 21 of a well known type. having: an operating lever 22, may be provided for connecting and disconnecting the pullev 13 with the shaft 1% and thus startin; and stopping the machine. In order to utilize a part of the drive for the pump as a drive for the rotating table 10, it is new r v to employ a speed reducing transmi... on. To this end, as shown in ligzs. l-'lto 10 inclusive, the shaft 14 is providcu at one end with the bevel pinion 23. which engages the bevel gear 247 on vertical shaft The latter extends into a casing; 26 which holds the transmission parts. Mounted on the shaft 1s a pinion 36 which engages each of two pinions 37 fast to studs 28 rotatably mounted in the disk 29, which is loosely mounted on a hub 30 forming part of the casing 26. Reduced extensions 31 from the studs 28 extend through a horizontallj, disposed gear 32, the centers of said extensions being eccentric to those of the studs. Surrounding the. gear 32 isthe intcriorly toothed annular disk 33, the opening through which is of somewhat greater diameter than that of the gear The said disk is supported in a member 34 which is fast to a shaft 3'55 carrying pinion 36. The rotation ot the shaft '25 causes the pinion '17 to be rotated and this causes the gear 32 to be moved so thatpthe centers of the extensions 31 will fOllUWifill lsifll'ltlally elliptical paths. This will cause the teeth on op posite sides of gear 132 to alternately engage the teeth r t the annular dish, and the result lar water cooled plate BEST AVAILABLE coP will be that the said disk will be driven at a very small fraction of the speed at which the shaft 25 is driven. It will be observed that the upper me'mber ill, as well as the lower member 29, is exterior-1y toothed. This alfords a means of utilizing the transmission as a clutch. As shown in Fig. 15, a spring pressed pawl 3'7 engages with the teeth on the member M. A. pawl 38 is provided for the lower member operated through a lever 39 attached to arm l0, which is in turn attached to the rod carr ving the said pawl. As shown in Fig. 16, the said pawl is in engagement w ith,the

2t) and this is Said teeth on the disk '29. and this prevents the rotation of the said disk. Under these conditions the upper member ill will be rotated in a counter clockwise direction and the pawl 37 will ride upon the teeth. However. when through lever 39, the gear will tend to rotate around the annular disk 33, which will remain stationary. The lever 39 is antomatically operated in a manner hereafter described. taunmunicatcd to the table 10 by a train of gears l1. l2, l3 and ll, as shown in Fig. 12. which may be such as to further reduce the speed.

Referring to seen that there are provided in the specific machine shown eight mani'l'olds 45. each" of which are adapted to receive the cxhaust tubes of four lamp bulbs lb. The said manifolds are suitably supportcd by clamps 4:7, 0

which are carried by brackets &8 supported upon standards il carried by the table 10. Supported upon the brackets 48 is the annu- 50 which extends entirely around Figs. 4

fold to is )rovided on its u )er side with 110 l l l tour apertures containii'ug rubber stoppers 51 which receive the exhaust tubes 52 of the lamps. The manifold may also contain, a trough 53 containing a suitable dehydrating agent. Removable and air pers M are provided for each end of the said manifold. vLeading from the bottom of the manifold are two ports 55 and The former is connected by means of rubber tube 57 to the tube 59 in a central valve comprising the movable member 60 and the stationary member (31, as shown in Fig. 33. The port. 59 communicates with the annular passage 69., the

bottom of which is connected to a passage 125 (S3 communicating w th the pipe 6a leading the pawl 38 is thrown out The motion of the pinion 3G is Fig. 1 and others, it will be the machine and serves as a 'bottom for the heater hood, as well as for tight stop- 15 58 leading to the port The 13 0 BEST AVAILABLE'COP outlet of said pump'is connected to a trap (ill-which is connected by means of tube 70 to the port 71 111 the movable member (50 of the central valve. T he port 71 is connected to an annular passage 72 which is connected.

at the bottom thereof to the annular passage 73 communicating with the pipe 74 leading to, a backing pump (not shown). The moi able member 60 of the central 'valve'is conncctecl to and moves with the annular trough 75 which contains oil for sealingthe joint between the movable and stationary mom bers of the said alre. The isaicl trough is connected in turn. by means of brackets 76 to standards supported upon the rotary table 10. A certa n amount of the oil containecl. in the trough75 flows out oi thc bottom thereof and serves to lubrieate the bearing of the said trough-on the central.

"ried from the strainer by means of a pump in clctail in Figs. 17 350320 inclusive.

81 driven, for. instance, as shown in Fig. 14, by the bevel-gear 24:, to'the upper trough 75.

The clamping mechanism which operates upon the rubber tubes 57 and. 65 for the rough and final pumps respectively, is shown best in Figs. 9 and 17 to 20 inclusive. Suitably supported by'thebrackets l8 and carried by the. rotating table by means oj t he studs 82, are the clamping members s'hppngn c said clamps each comprise a stationary member or back 83, in which are swiveled the movablc'members 84 and 85. Feel of these carries av stop 86 comprising pins p ing through slots'in the member 83 and serving to limit the outward throw of the said movable member. The member 84: has pivoted in a slot 87 in. the samea. latch 88 use.

which iii one position engages a pin89 located in a slot in themember 88.

As shown in Fig. 20, the latch 88 is bent upwardly at its outer end with a depending lug 90. Pivoted in a slot 91 of the member 83 is a latch 92 engaging a pin 93 of the member 85. The said latch is connected to the hitch 88 by springflQ l. The other end of the latch 9:2 is'con'nected by means of pivotccl ever 35 to a 'pivoterlxlcver 96', which is pi votiiilin a slot in the member 83. The outer cntl 97 of the member 96 is lispose'd bacli: of and on a level with end of the latch. 88. As shown in Fig. 9. an arcnate member 98 is supported through bracket 99 by the base of the machine. One and of the said member carries a trip 100, which is disposed in the path of and is adapted to engage the end of the latch '88 forcing it to the right and releasing it from the pin 89, thus'allowin; the member 8-1: to fly open. This opens a i connection to the-rough pump. Atthe other end of the member 98' is disposed. a block 101. the inner face of which is oblique. This face engages roller 102 carried by tlio member 8% and "forces the said member to,v close and the latch 88 to again engagethe pin 89.

A slight further movement causes the enrl 9; of the lever 96 to be engaged by the sanl block, and this causes the latch 9:2.

to be released and the member 85 to open.

This opens the connection to the final pump.-

.is shown in Fig. 9, the connection to the final pump remains open until a point-M reached. at which point it is closed bytheoperator. who seals of? and removesthe-exsw iaustecl lamps.

The means for heating the lamps 'cluring which communicate with the annular pas-' sage 109, which in-turn connects with the conduit 110 rotatably mounted on the block 110. the said burner.

which the operator is located, and which is This is connected by pipe 111 with" The heater hood extends around the machine as shown in Fig. l. ex cept for a space, opposite the point Mat substantiall} coextensive with the length of the manifold. As the operator removes the exhausted bulbs and replaces them with new lmlhs, it is necessary for the heater hood to he turned to include the new lamps and to expose the next lot of exhaustion lamps A stheengls of the said hood are provided with (lOfiif-lfil and 113, as shown in Fig. 1 and others, it is necessary that means be pro vitled for opening these doors prior to the rotationof the hood and for closing. then".

afterward. It is desirable also that the rota-1 tion. of the hohcl be automaticallycontrolled bv the starting of the rotation of the; table 10 by the operator. This mechanism is" shown in detail. in Figs. 21 and 22.

By reference to Fig. 3 is will be seen. that I the shaft 105. wl'iich carries thehood, carries a collar 11% to which is attached one end of 'a helical spring 115 surrounding the said shaft anal attached at its other end tothc stationary collar 116. The hootl 183, as shown'in Fig. 21. carries a pivoted latch 117, which engages one of av series of lugs 118 extending from the brackets 48. carried by the rotary table 10. While in engagement with one of the said lugs 118 the hood is :rotaterlwith the table and the spring 115 is wound up. A series of eight mechanisms li is provided so that the operator may shift the heater for each set of lamps. Pivotally mounted on each of the standards '19 is an operating lever 119, one end of which is indented to receive the end 120 of an arm extending from the shaft 121 mounted in the said standard 49-and carrying an arm 122, engaging and supporting the end of stop pin 123 slidably supported in the bracket 48. The otherend ot' the shaft 121 carries an arm 124, the end oi which carries the roller 125. The hood 103 has pivotally supported at the bottom thereof a bell-crank 126, one end of which normally engages the pin 123. ()n the other arm of the hell'erauk is loosely supported a depending rod 127, which is normally held in the position shown. ihe said rod has attached thereto a spring 128 and in the position shown said spring is in tension. The upper part of rod 127 carries a pin 129, which. upon the drop of the said rod as hereinafter described, engages the end of the latch 117 and opens the same. The bell-crank 126 is connected by means of the pivoted lever 1310, bell-crank 131, strap 1:12 to arm 133 of the pivoted sleeve 134, which carries the arm 135 attached to the door 112. The said sleeve 134 also carries an arm 136 to which is pivoted the rod 137. which extends to a correspomliug arm 136 attached to a sleeve 131 similar to that described.

ltv will be apparent that when the lever 119 is pressed inwardly the arm 120 will be, released causing the arm 122 to lower and with it the pin 123. Spring 1% then acts to lower the rod 127. thus causing the doors 112 and'113 to he opened through the levers and other connections actuated through the hell-crank 126. During the downward movement of the rod 121' the pin 129 strikes the end otthe latch 117. releasing the same. The spring 115 then acts to rotate the hood until the latch 117 strikes another stop 119. and the end of bell-crank 126 engages another stop 123. which is in the raised position. This results in the crank 126 to close the doors 112 and 113 and to raise the rod 127. The resetting of the pin 123, which has just been lowered, is accomplished by the engagement of the roller- 125 by the lug 138 on the member 99. which raises the same and the arm 126. causing the latter to drop into the indentation in the end of the lever 119 and to be there held so that the arm 126 and the pin 123 are kept in raised position. As shown in Figs. 4. 10 and 11, a dashpot 137, comprising a piston 138 carrying a rod having aroller atone end which rides in turn upon the inclined blocks 138" is attached to the heater hood and takes away the jar which would otherwise occur upon its stop.

It. will he understood that the machine is periodically stopped to permit the operator actuation of the bell to remove the exhausted lamps and to put in certain new ones. This is accomplished by the. blocks 13) carried at the end of one of rods 127 striking the end of arm 140 mounted on a shaft passin through sleeve 141, and which is connected %y the rod 39, which has been hereinbefore described, and whichnctuates the clutch. Upon the lever 119 being pressed by the operator and the con uent dropping of the rod 127, the block 139 0 cars the arm 110 and the clutch is thrown in.

Before the lamps are removed it is necessarv that they be tested to determine whether they have been properly evacuated.

The ordinary way of doing this is to make the ends of the lamp the terminals of a high tension electric circuit. If the lamp is properly evacuated there will be no discharge. However, if there is any air in the lamp, a visible discharge will take place.

The present invention comprises means for automatically submitting the lamps to l test when they reach the removal position. his means is shown in detail in 1* igs. 28 and 29. The leads 141 and 142 are colinected to a source of alternating current, for instance, a lighting "circuit. The lead 142 is connected to the armature 143 of a vibrator, which is connected to the ground. The lead 141 is connected to the binding post 111, which has attached thereto the spring contact 145. A correspomling spring contact is attached to a binding post 146, the circuit from which is divided, one branch being connected through a lamp 147 and the coil 118 of the vibrator to the around. The other branch is connected through the condenser 149, resistance 150 contact 152 of the vibrator. One terminal of the secondary 153 of the induction coil is connected to the manifold 1-15. The other terminal is electrically connected to an arm'154, which carries a yielding .contact member. such as chains 155, which in their lowered position of the said arm engage the tops of the lamps. The arm 151 is insulated from and supported in the holder 156, which is pivoted between two arms of s ider 104, as shown in Figs. 4 and 28. he holder has a depending lug 157 carryin and insulated from the contact 158, w ich in the position shown, is located between and engages the spring contacts 145. The holder 156 carries the rearwardly projectingnected by spring 160 to the. hub 161 of spider 104. The hub 161 has passing therethrough and engaging the lug 159' a pin 162, the other end of which carries a re ler 163. The. said in is slidable on the pin 164 depending ii'om hub 161. heater hood is released, the roller 163 travels in a serrated ,cam member 164', which, as show n in Fig. 3, is carried by When the lug 159, .which is con-- table 10.

The-up and down motion of the pin 162 due to the cam 164:, causes the contact 158 to'be swung into and out of engagement with the spring contacts 145, thus making and breaking the circuit. The make occurs as the heater hood ends its movement to include new lamps and the break occurs immediately thereafter, due to the roller 163 droppinginto a depression-in cam 18%. There is a depression in the cam 164 for each set bf bulbs. lhe depressing and raislag of the arm 154. and the engagement and disengagement of chains 155 with the lamp bulb occurs simultaneously with the makeand break of the circuit. If desired, the automatic parts may be supplemented by means, such as the cord 166, which may be grasped by the operator to lower thearm 154 byliand. v

The brackets 165 supporting the cam 16% also serve to support, as shown in Fig. 3,

a tank 167 holding water for coolingpurposes. The water is circulated as by pump 168 driven by the final vacuum pump drive from tank 167 to the hollow plate 50 which serves as a bottom bafiie for the heater. After passing around and through the plate the water passes to a perforated pipe 169 from which it drips into tank 167 being cooled by contact with. the air. As shown in Fig. 23, a central stationary pipe 170 having an upward extension 171 and con nected to the water main through valve connections 172 may be provided for supplying water to the tank 167. The conduit between 171 and the tank is not shown.
